The study of a food web roughly covering the shelves of Puerto Rico and
adjacent areas by Bascompte et al. 2005 indicated that declines in several
species of sharks at the predator end, and herbivores such as parrotfish at
the prey end, would likely have the most substantial impacts on the
The role of the sharks was further confirmed by an analysis of the same food
web (from one of the earliest Ecopath analyses) by Rezende et al. from the
standpoint of compartmentalization. The role of parrotfish was confirmed in
the new study led by Jeremy Jackson.
The above food web analyses go beyond the older, mostly guesstimated,
declarations of 'keystone predators'. However, the idea of a group that
would strongly impact the ecosystem when reduced seems to fit that concept.

Subject: [Coral-List] Keystone coral species in the Panama region
Is anyone able to point me in the direction of keystone coral and
invertebrate species within the Panama and or Caribbean region please? I
can't seem to find anything in the literature. Also, if anyone knows of any
resources in regards to reef composition within the Panama region, in
particular the Bocas del Drago region within recent history? I'm looking to
do a phase shift analysis of the area and any information would be greatly
